Adding Production well and Horizontal injection well in CO2 Sequestration model

[Vishal]

Greeting Everyone,

Currently, I am using CO2 sequestration model in MRST in which i am experimenting on Johansen model. 
I just wanted to know the followings:

1. How to add production wells and Horizontal injection well in the Johansen model, as only adding injection wells option is given in the interface?
2. Also, I need reservoir pressure, saturation and relative permeability plot of the simulation.

It would be helpful if you could provide me the relevant code for these process. 

Looking forward to your response.

Warm Regards,
V

Dear Vishal,

Are you using the VE simulator in mrst-co2lab, or perhaps a full 3D simulator?   Horizontal wells are not supported out of the box, though you can create a somewhat similar effect by inserting separate wells for each gridcell along a line and specify a correpsonding set of rates or pressures. 

I believe production wells should be relatively straightforward to add.  You can use the `addWell` function as before, but specify a negative rate (for rate-controlled wells) or a sufficiently low bottom-hole pressure (if pressure controlled wells).    The 'example VEJohansen' script does have some code that demonstrates how results like reservoir pressure and saturation could be visualized.  For relperm, the answer will depend on whether you are running a VE or 3D simulation, as the interpretation of "relative permeability" is different in the two cases.

Let me know if you need further explanation.

Best regards,

Odd

Thank you for your response.
Actually, I am using VE simulator in CO2Lab and as for the production wells I will try applying your approach.

Thank you,
Vishal
